To all whom it may/ concern Be it known that I, WAsI-IINGTON L. CAL- HoUN, a citizen of the nitediStates, and a resident of Tarrytown, in the county of Montgomery and State of Georgia, have invented certain new and useful Improvements in Cotton-Choppers, of which the following is a description.

This invention relates to certain new and useful improvements in cotton choppers, and the object of my invention is to provide an implement for Cutting openings in a row of growing cotton plants, so as to' leave them in bunches or hills, the machine being automatic in its operation, though provided with a manually Controlled trip, arranged to throw the chopper blade out of action.

`With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described and finally pointed out in the appended claims, it being further understood that Vchanges in the specific structure shown and described maybe made within the scope of the claims, without dcparting from the spirit of the invention.

ln the accompanying drawings forming a part of this specification and in which like numerals of reference indicate similar parts in the several views, Figure 1, shows a side elevational view of a cotton Chopper embodying my invention. Fig. 2, shows detail of the hanger bars. Fig. 3, is la section on line 8, 3, of Fig. 1. Fig. 4, is a top view. Fig. 5, is a sectional detail throughthe supporting,` wheels. Fig. 6, shows a detached detail disclosing the method of securing the striker head to the yoke. Fig. 7, shows a detail partly in section disclosing the arrangement of the brace lbar and its connection to the hanger bars. v

In my present invention, I provide a cotton chopper including a main drag bar 1, which at its rear end is provided with a bolt opening arranged to receive the pivot bolt 2. At the forward end, the bar is curved upward as shown in Fig. 1, and provided with the openings w, arranged'to be engaged by the clevis hook, forming` a part of the harness of the animal draggintz the cotton Chopper. Pivotally held upon the pivot bolt 2, are two similar carrying arms 3, each arm having an apertured head 4, within the apertures of which is held a securing bolt 4 passing through a suitable opening within the end of the drag bar. At theirilower ends these carrying arms, as shown in Fig. 5, ,give support to the supporting wheels 6 which are secured to the spool 3' the spool and `wheels revolvin; upon the shaft 2'. rlhe shaft 2' is held in position by means of the cotter pins 4'.

As shown in Fic. 7 each supporting` wheel 6, is provided with a plurality of openings b, and arranged to be removably held within these openings b, are the striker pins 7 each Vof which has a stop shoulder 5'. These Striker pins are held in position by means of the cotter pins12. Adjustably held to the drag bar 1, are the two similar hanger bars S which are clamped upon the bar 1 by means of lthe bolts 13. At their lower ends these hanger bars 8 support the bolt 1.4. Pivotally held upon the bolt 14, is the yoke 9, comprising two similar members which are slightly curved and at their lower ends are held in parallel spaced relation by means of a block 15, the ends being; clamped to the block by means of the bolts 16. These bolts also secure the Striker head V10 preferably made of sbeet metal and arrang'ed to be normally in the path of the striker pins 7 to the yokeas shown in the drawings. Near the upper end, as shown in Fin; 7 the yoke 9 is provided with the stop'bolt 17 arranged to strike upon the upper edge. of the drag bar 1. This stop bolt- 17 also supports the colter bars 12 which at their lower ends are provided with the share 18. Intermediate ofv-their ends the colter bars are provided with the bolt 19 upon which is held the brace bar 11 which bar at itsupper end is secured 'yoke 9 and the colter bars 12 are provided with a plurality of openinzs so that the colter bars 12 can be adjustably secured to the bolt 14. Secured at their lower ends to vthe drag bar 1, are the two similar handle bars 20 which near their upper ends are strengthened by means of the brace bars 21 and 22. At their lower ends these handle bars are secured to the drag bar by means of the bolt 23 as 'disclosed in Fig: 4. Near their lower ends these handle bars lgive support to the rock shaft 25 which has an ex'- tending, arm 26 and an ear 27. Extending from the lower end of the arm 26 is the chain 28, which has its other end secured within the bight portion of the yoke 9 as clearlv shown in Fig. 7 Extending from a pin 80 secured within the lower ends of the handle bars 20, is the spring 31 which has its other end securecl to the bight portion of the yoke 9. This spring 31 normally forces the pin 17 into engagement with the drag bar 1, as shown in Fig. 7. Secured to one of the handles by means of a pin 32, is the trip lever 33 to the end 34, of which is secured the connecting rod 35, which has its other By means of 'this trip lever the colter share 18 can be drawn out of the ground by hand. Clamped lupon the forward end of the drag bar 1, lare the upper and lower clamp plates 36, held in position by 'means of the two bolts 37, shown. in Fig. 4, Extending from each bolt 37 and pivotally held thereon, is a side bar '38, and each bar near its rear end, is provided with two bolts 89 and 40. The bolt 40 gives pivotable support to the shovels 41, which have the enlarged heads 42, having suitable openings as shown in Fig. 1 so that these shovels vare adjustably secured Zto 'the side bar 38. These bolts in addition give support to the brackets 48, which are Ibent at right angle and {are'provided with slots as shown 'in Fig. 4, to adjustably receive the ola/mp vbolts 45.

As 'shown in Fig. 1, .the securing bolt 5 gives support. to the angle `vbars 46, which also'v have their ends slotted to adjustably receive the clamp bolts 45. The position of I the fangle' bar-s 46, is also 'shown in Fig. 3.

In addition to 'holding 'the brackets 43 to the angle "bars 46 the bolts pass through the lower ends of the standards 47, which standards at their Zlower ends are `secured to the handle bars Q0 by means of bolts 48. By means 'of this construction 'the side bars can b'e swung 'toward or away `yfrom the drag bar 1. The openings are so arranged that the `share 18 can be tripped once,twice or three times or four times to each revolution of the 'wheel 6.

It 'is 'of lcourse unders'tood that whileI have de'sc'ribed my device 'as a cot'ton chopper that 'the same 'can b'efused in connection with other them out.

My xc'otton 'chopper is simple'and in'expensive in 'construction and both 'dur'a'ble and efii'cie'nt in 'operation and the adjustmen't V'ot the several adjnstably secured 'members lcan be 'e'ifecte'd with ease, 'accuracy and 'despa't'ch. a i
